Hi,

The following vulnerability was published for librsvg.

CVE-2026-96889[0]:
| A flaw was found in librsvg. When processing an SVG document
| containing nested XML inclusions (Xincludes) with duplicate entity
| declarations, a use-after-free error can occur. This vulnerability
| arises because the library incorrectly frees an XML entity that is
| still in use by the parser. An attacker could potentially exploit
| this to cause a denial of service or execute arbitrary code.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
